IGU Quality Control

Non Destructive Gas Measurement for Insulating Glass Units

Ensure your insulating glass units not only look good but perform reliably. Sparklike provides industry leading non-destructive gas measurement solutions that deliver accurate real time data on insulating gas levels, thickness, and IGU quality. Gas measurement is a critical part of modern insulating glass unit quality assurance and production control.

Insulating gases such as argon and krypton significantly improve thermal performance and energy efficiency in double and triple glazed units. Without proper measurement, insulating glass units can lose up to thirty percent of their insulation performance. Visual inspection alone cannot verify gas content or long term performance quality.

Why Gas Measurement Matters in IGU Quality Control

Insulating gas as a performance quality metric

Gas fill rate is a functional performance parameter that directly affects thermal insulation, seal durability, and long term energy efficiency. While visual and optical inspection systems are essential for detecting surface defects, they cannot assess internal gas concentration or seal integrity. Gas measurement completes the quality control process by verifying actual insulating performance.

Gas measurement across production and lifecycle

Sparklike devices are used globally by insulating glass manufacturers, quality control laboratories, façade specialists, and inspectors to verify correct gas filling during production, detect under filled or leaking units, support warranty claims with measured data, and evaluate insulating glass units during installation, renovation, or reuse.

Beyond Visual Inspection

Quality Control in Insulating Glass Manufacturing

Visual inspection systems and optical scanners are effective tools for detecting visible defects such as scratches, inclusions, or dimensional deviations. However, they cannot evaluate internal insulating gas content or thermal performance.

Gas measurement adds a functional performance layer to quality control by verifying insulation efficiency, seal quality, and compliance with performance requirements. Together, visual inspection and gas measurement form a complete insulating glass quality assurance strategy.
